12.7.3 Frequency Level Detection
This function is used to detect the difference between the output frequency and
the setting frequency. An indication signal will be generated ONLY when the out-
put frequency is HIGHER than the lower limit of the frequency detection level.
The indication signal can be used for further engineering in the application.

The selected digital output signal and status are as below:
●
[E2.15] = 5: Frequency level detection signal (FDT1)
– Active when 'Output frequency' is higher than [E2.71]
– Inactive when 'Output frequency' is lower than [E2.71] - [E2.72]
●
[E2.15] = 6: Frequency level detection signal (FDT2)
– Active when 'Output frequency' is higher than [E2.73]
– Inactive when 'Output frequency' is lower than [E2.73] - [E2.74]
